A key coalition of 30 labor unions representing city of Detroit workers ratified new concessionary contracts this week, less than a week before Gov. Rick Snyder is expected to decide on appointing an emergency manager or reaching a consent agreement with the city’s elected officials.

“We want to fix Detroit together,” Ed McNeil, special assistant to President Al Garrett, AFSCME Council 25, who cochaired the coalition’s negotiating team, said in announcing the agreements today.

“This is not a short-term fix but a long-term process to turn the city around.”

Union negotiations are considered the cornerstone of any plan to save the city from financial ruin.

City Council is expected to approve the concessions next week.

But whether those concessions are enough remains an open question.

Under the current agreement, the city would save about $54 million a year in concessions — less than half what Mayor Dave Bing originally wanted.

Other savings include $14 million in layoffs and about $100 million in new revenue by aggressively collecting past due taxes and parking tickets, but those were plans already under way before the negotiations.

Still, union leaders stepped up the rhetoric against more state intervention, saying the concessions show that city leaders and workers are willing to make big sacrifices for the survival of the city.

“When the union members see a need, we step up each and every time to meet that need,” said Richard Mack, the coalition’s attorney who helped with the negotiations. “We are going to make sure the city gets back in the black within a year.”

But even if council approves the new labor deals, the state still says it has the authority to wipe out the contracts under an emergency manager.

Bing’s administration called the ratifications “historic and precedent-setting.”

“These ratified agreements, reached before their existing contracts expired, reflect how labor and management can work together in a fair and constructive way,” said Bing Chief of Staff Kirk Lewis. “The agreements also provide checks and balances that hold both unions and Mayor Bing’s administration accountable.”
